  2. Outline Design Review Key Design Components Demonstration Complete Design Overview Future + Timeline

  3. Problem and Solution Reliable Quantitative Data in Physical Therapy (PT) can only be Collected with a One-on-One Patient/Therapist Interaction Create a simple,inexpensive, and portable device that can accurately measure physical therapy related motion

  4. Block Diagram

  5. Progress Since MDR • Beagleboard platform: • Wireless USB interface • Processing sensor data in Python • Audio feedback • Shell scripts for files and memory

  6. Outline Background Key Design Components Demonstration Complete Design Overview Future + Timeline

  7. Wearable Sensor • Zigbee Transmitter • 45mA @ 3.3V • ADXL335 Accelerometer • 4mm x 4mm x 1.45mm, 350uA @ 3.3V • 9V Battery-Power Supply • Voltage Regulator 3.3V

  8. Mounting Wireless Sensor • 2 XBee Transmitters • 2 Accelerometers - ADXL335 • Power Source – Coin Battery Rechargeable • Lithium Coin Cell • 3.7V @ 200mAh • Inexpensive

  9. Processing and Display • Counterpart XBee wireless receiver plugged into USB on BeagleBoard • All pitch values plus timestamp logged into .txt file • Gobetwino software listens to serial port for specific commands • Logs all pitch values with timestamp in .txt file • GNU Octave processes info in .txt file • Plots Pitch vs. Time
